Tunable Alignment for All Polymer Gel/Solvent Combinations for the Measurement of Anisotropic NMR Parameters

A stretching apparatus (see figure) with arbitrary scalability of alignment strength is introduced for the measurement of anisotropic NMR parameters, which works for practically all polymer gel/solvent combinations. Its use is demonstrated in applications involving the steady incrimination of residual dipolar couplings, the distinction of enantiomers, and the conformational analysis of organic compounds.
